Oaks Bottom Wildlife Refuge Professional Review and Guide
"Drive, bike, or take the bus to this 168-acre wildlife refuge located in the heart of the city. Once destined to become an industrial site, in 1988 Oaks Bottom became Portland’s first formally dedicated urban wildlife refuge. Oaks aren’t abundant here, but cottonwoods are, along with eagles, waterfowl, and great blue herons, Portland’s official bird. And expect a lot of surprises, too, from a charming historical amusement park to a beautiful giant mural."
